Plasma carotenoids, tocopherol and retinol research in the age of 35-74 years in six European countries.
Plasma carotenoids, tocopherol and retinol research in the age of 35-74 years in six European countries.
Nutrient status may change with age. We analyzed plasma carotenoids, α- / γ-tocopherol and retinol, and compared them with age, demographic characteristics, and eating habits (assessed by a short food frequency questionnaire) in a cross-sectional study of 2118 men and women (age-stratified 35 -74 years) of the population in six European countries. Older age was associated with lower lycopene and α- / β-carotene and higher β-cryptoxanthin, lutein, zeaxanthin, α- / γ-tocopherol and retinol levels. Significant correlation with age were observed for lycopene, α-tocopherol, α-carotene and β-cryptoxanthin. Age was inversely associated with lycopene and this association remained in the multiple regression model with the significant predictors (covariates) his country, season, cholesterol, sex, smoking status, body mass index (BMI (kg / m²)), and food habits. The positive association of α-tocopherol with age remained when all covariates, including cholesterol and the use of vitamin supplements were included (1.7% vs. 2.4% per increase in the age of five). The association of higher β-cryptoxanthin with a higher age was no longer statistically significant after adjustment for fruit consumption, while the inverse association of α-carotene with age in the fully adjusted. We conclude from this study that age is an independent predictor of plasma lycopene, α-tocopherol and α-carotene.
These investigations can also be carried out by the laboratory "World Health Laboratory".
